Wren H Series, Руководство по эксплуатации

Страница: 10 / 53

After determining the desired torque, use torque conversion charts on page 5 to determine
the pressure that is necessary to achieve that torque.
1. Connect the tool to the power supply and turn the pump on.
2. Depress the advance remote control button causing the pressure to be shown on the
gauge.
3. Adjust the pressure by first loosing the nut that locks the pressure adjustment handle and
then rotate the handle clockwise to increase the pressure and counter clockwise to
decrease the pressure. When decreasing pressure,always lower the pressure below the
desired point and then bring the pressure gauge back up to the desired pressure.
4.When the desired pressure is reached, retighten the lock nut and cycle the tool again to
confirm that the desired pressure setting has been obtained.
SETING THE TORQUE
OPERATING THE WRENCH
1.Place the ratchet hex on the nut. Make certain it is the correct size for the nut and
that it fully engages the nut.
2.Position the reaction surface against an adjacent nut, flange or solid system
component. Make certain that there is clearance for the hoses, swivel, and inlets. Do
not allow the tool to react against the hoses, swivels or inlets.
3.After having turned the pump on and presetting the pressure for the correct
torque, depress the remote control advance button to advance the piston assembly.
If the notch in the piston rod did not engage the retract pin in the ratchet engage the
pin automatically during the first advance stroke.
4.When the low profile cassette is connected to the housing and the wrench is
started, the reaction surface of the wrench will move against the contact point and
the nut will begin to turn. Once the piston reaches the end of its stroke depress the
remote control return button to retract the piston.
5.Continue this cycling operation of advance and retract until the nut is no longer
turning and the pump gauge reaches the preset pressure. The piston rod will retract
when the retract button is pressed and under normal conditions, an audible
“Click”will be heard as the tool resets itself.
6.Continue to cycle the tool until it “Stall”and the preset psi/torque has been
attained.
7.Once the nut stops rotating, cycle the tool one last time to achieve torque.
